If you have SIM Card Lock enabled, then you can change your SIM PIN. (Check with your wireless operator's Customer Care department to determine if there is a default SIM PIN.)

1. From the SIM Center screen, scroll to the SIM Card Lock group box.
   
2. Select the Change SIM PIN button, as shown above. The Change SIM PIN dialog box opens.
   
3. In the text fields, type your old PIN, the new PIN (4-8 digits), and then your new PIN again to confirm.
4. Select Submit to dismiss the dialog box and save your new PIN. You will receive a confirmation dialog box to let you know your PIN was changed successfully.
